Period one week after ovulation??

Courtney

Hey guys! So I’m super confused. PCOS here. Have been TTC for 2 years now. Have been taking Metformin 500mg 3X daily since August, and also take Clomid when prescribed. I had a visit with my OB on January 23rd to monitor follicles and to see when I will be ovulating. OB said I had 2 really good follicles and should ovulate within the next 3 days. So my predicted ovulation this month was the 23-26, so I’m currently 5-7 DPO. For the past couple of days, I have been spotting brown and now AF just arrived. 😭😭 I’m so confused. Is it normal to get AF not even a week after ovulating?? Please help!!
